Gauss's law (or Gauss's flux theorem) is a law of physics. The law is about the relationship between electric charge and the resulting electric field. In words, Gauss's law states that:
- The net electric flux through any closed surface is equal to 1⁄ε times the net electric charge enclosed within that closed surface.[1][2]
The law was created by Carl Friedrich Gauss in 1835. However, it was not published until 1867. It is one of the four Maxwell's equations on classical electrodynamics. The other three are Gauss's law for magnetism, Faraday's law of induction, and Ampère's circuital law.

Electric flux through an arbitrary surface is proportional to the total charge enclosed by the surface.
No charge is enclosed by the sphere. Electric flux through its surface is zero.
